The leases in my area are for 30 years with an option for an additional 30 years. with a inflation rate of 2% or the CPI.
The tower rate (at a point in time that I have data from) was $2,500 per megawatt and each is 1.65 to 2.1 megawatt. Additional lease fee is for access roads
, buried cable easements and other needed infrastructure. Roads and buried lines may account for $1,200 to $2,000 per tower additional.
The towers sell with the land and can not be separated.
Lease rate may go up is capacity is at greater than a set point, but can not below the stated amount.
There have been very few sales with towers. Based on the land sales and reported tower income the cap rate was about (6 to 15%).
The value derived was about $70,000 per tower (larger units) based on comparing with to without sales and this compares to
a present value using an 8 to 10% cap rate (8% @ 30 yrs or 10% @ 20 yrs).
On the sales in crop land area this added about $341 to $1,200 per acre depending on tract size 80 to 600 acre sale.
The question is will they be here 30 years from now? The discount rate may need discounted for failure probability %. Some wind farms are in bankruptcy
and others appear strong.
This data is from a small sample so the whole market is likely a lot more fluid. I have heard but not seen data on their minimum needed rate of 10 cents per KWH.
This is still above out local rates. Many companies are required to use a cetain percentage of renewable energy.
Rural residential values may have increase because the roads were improved to carry the weight of the construction equipment, a demand by the county.
A house can be no closer than 1,800 feet from a tower. The tower posts are about 250 to 495 feet and each blade is about 125 to 160 feet long. Maximum speed us about 12-20 rpm
or a tip speed of about 150 to 235 miles per hour.
There are many within a half mile of the home farm and can not be herd unless you are under one on the vast majority of days. On very quiet days with little t o wind
a slight whir can be heard, but on very low wind days few run. They are turned off unless they have the power sold. Most of the time less than half the towers are running
on a few occasions all have been seen running.
Some wind farms pay on royalties and some do not, so the formulas may be vastly different from windfarm to windfarm.
